Feature:1. Stable performance, it has strong antiinterference ability, and has a variety of applicable types of cables. It is an indispensable testing tool for telecommunication engineers, wiring engineers, and network maintenance personnel.2. Tracking function, it can track the line from RJ11, RJ45 interface, other metal conductors can be tracked through the adapter, the sensitivity is adjustable, the signal is strong and the distance is long.3. Noncontact type, it can use noncontact method when performing AC voltage detection, can detect AC voltage above 48V, and does not need to strip the sheath, which is convenient and quick.4. It can be directly searched with any type of weak current equipment such as Ethernet switches, routers, etc. It can fully detect the order of the network cables, and is equipped with lowvoltage prompting and lighting functions.5. Small in size, it is lightweight and portable, can be easily handheld to test in various situations, to help you detect the cables you needcan be used as a good helper for you.Specification:Item Type: Line FinderMaterial: ABSModel: WT-58DLTransmitter Power Supply: 1x9V 6F22battery (Battery Not Included)Receiver Power Supply: 1x9V 6F22battery (Battery Not Included)Purpose: It is suitable for testing network cables and telephone lines.ModelWT-58DLSpecial FunctionWith Red Light Pen FunctionTransmit A SignalDigital Signal (No Interference and No Noise)Applicable EquipmentEthernet Switch/Router/Optical Cat and Other Weak Current Equipment Live Line Hunting and TestingHunting FunctionTraceable Type: RJ45, RJ11 and Metal WireLine FunctionDetect Line Breakpoint, Short Circuit, Line Sequence (Network Cable)Line Level DetectionLine Level Positive and Negative DetectionTelephone Line Status DetectionDetermine The State of The Telephone Line at Work (Ringing Indicator Light Prompt)On-Off FunctionDetermine Whether The Cable is ContinuousPOE Switch Withstand VoltageThe POE power supply switch can directly trace the line with power, and the DC voltage should be less than 60V.Switch Port PairingTransmitter Direct Detection and Switch Port Network Line SequenceAccessoriesEarphone/Network Cable/6P Clip CableSignal DistanceApprox. 0-300m / 0-984.3ftOperating Temperature0~40, 80% Relative Temperature (Non-Condensing)Storage Temperature-10~50, 80% Relative Temperature (Non-Condensing, without Battery).Package List:1 x Receiver (Battery Not Included)1 x Transmitter (Battery Not Included)1 x Earphone1 x Cable1 x Clip Line1 x Toolbag1 x ManualNote:Do not use this product during thunderstorms, dampness, and thunderstorms.
